Stocks: Earnings season springs

Investors will head into the second week of the year ready to move beyond fiscal cliff chatter, and into the earnings season.

The U.S.' largest aluminum producer Alcoa(AA) will kick off earnings season on Tuesday, after the closing bell. Apollo Group(APOL), WD-40(WDFC), Texas Industries(TXI) and Wells Fargo(WFC) are also reporting throughout the week.

Investors will also get a sense of whether the fiscal cliff impacted companies' operations, as many business leaders and economists were anticipating.

Economic data is relatively light this week. Reports on trade are scheduled to be announced throughout the week, including trade balance and import and export prices.

The S&P500 fared even better, finishing at its highest closing level since December 2007.
